My mother has been diagnosed with stage 3 breast cancer (Her2) approx. 18 months ago. She is towards the end of her herceptin course. It is also our understanding that she has been suffering from thickening of her endometrial lining. It was simple hyperplasia and now the line has further thickened with bleeding. She is 57.

Wanted to know if she could go through Hysterectomy if prescribed by doctor? Any risk from hormonal perspective?
